摘　要:通过对三坐标测量机更换测量系统，改进、设计与此相配的机械部分，从而建立误差补偿模型，并进行误差测试，同时利用软件进行误差补偿。结果证明：本误差补偿方法能使测量机的空间精度提高2—3倍，且这种补偿方法简单可靠，为通过误差补偿提高三坐标测量机的精度提供了简单而有效的手段。[著者文摘]

Error Compensation to Three Coordinate Measuring MachineZHAO Tianehan , WU Hui , FENG Jun , WU Wenbing 1. Eleetromeehanieal School, Jianghan University, Wuhan 430056, China; 2. Beijing Nanhanglike Mechanic Co, Ltd, Beijing 100076, ChinaAbstract:Some modification to the three coordinate measuring machinec （CMM）, was accomplished with changing the measuring system and modifying the corresponding mechanical parts. A better error compensation model was constructed which applied software to measure the error. As a result, it increases the volumetric accuracy by 2 or 3 times. The method is convenient and reliable to improve the accuracy of the CMM through the error compensation.[著者文摘]
